The size, speed, location and angle of impact of the object with the Earth. A major factor would be if the impact is on water or land.
World annihilation comes to mind.
It is FAR easier to change the direction of an asteroid than to blow it up. All that is needed to accomplish the former is to nudge the asteroid a little off its collision course with Earth, and this could be done with some small explosions on the side of that asteroid. Blowing up an asteroid would be a complete waste of energy.
because they are big chunks of rock hitting your spacecraft
Any kind of collision, such as a meteorite or asteroid colliding with a planet, or an explosion of a star could be classed as natural disasters in space.
The result wold depend on the energy created by the collision. In most cases both objects would shatter into pieces that would spin away in a variety of new directions. If the asteroid collides with a much bigger object (a planet) then it will create an impact crater in the planet and the asteroid and a bit of the planet's surface will melt.
There is no way to avoid an impending collision.
Yes, if the asteroid is captured by the Earth's gravitational pull.
The Gr8 JAke
of course
dangerous
No. The moon is large enough that even a collision with the solar system's largest asteroid would not destroy it.
chunks of the core of a larger asteroid that was shattered by a collision.
You cannot "avoid" a collision; if the asteroid is headed this way, it will hit. They aren't steerable. Give us another 50 years or so, and perhaps we would be able to prevent it.
unless a big earthquake or big asteroid collision, no.
World annihilation comes to mind.
Rings around a planet are caused by a collision. This collision could occur from a moon crashing into a moon, a moon crashing into the planet, an asteroid crashing into a moon or an asteroid crashing into the planet. The resulting debris from the collision gets trapped in the planetary orbit, and hence, creates a ring system.
There are currently no known asteroids on a collision course with Earth in 2022.
